When I tried to search for "Superkid" using the english search I was awarded with no hits in the DB, but I managed to find the movie using a slightly different spelling, "Super Kid", what suprised me somewhat is that "Superkid" is listed as an alias as can be seen HERE, seems the alias "Superkid" only works when you search for it using the Big5 search

Try it now. Whoever entered it originally entered Superkid under Big5 not under English.

yeah works fine now, thx
